Dear all, I have an anisotropic point pattern, analyzed by means of directional correlograms, wavelets and Ksector functions. I wonder if anisotropy prevents the use of inhomogeneous K-functions. Thank you in advance, -- Domenico Giusti <dncgst at gnewarchaeology.it> GPG...

Dear all, I get "Error in nrank%%1 : non-numeric argument to binary operator" running > data("amacrine") > E <- envelope(amacrine, Kcross, "on", "off", nsim=19, global=FALSE) Envelope works fine running > E <- alltypes(amacrine, Kcross, nsim=19, envelope=TRUE, global...

Hi, convexhull is probably what you need. Best, On 11/18/2015 11:56 PM, Zhong-Yuan Zhang wrote: > Dear All: > > As a freshman, I am now analyzing some spacial data. > > I want to get the border of scattered spacial...

Hi all, I'm running wavelet analysis of anisotropy in point patterns using the PASSaGE software by Rosenberg et al. Rosenberg, M.S., and C.D. Anderson (2011) PASSaGE: Pattern Analysis, Spatial Statistics and Geographic Exegesis. Version 2. Methods in...

Thank you! P.S. I use to type the options, to remind me what I'm doing :) On 05/17/2016 11:08 PM, Rolf Turner wrote: > On 17/05/16 23:44, Domenico Giusti wrote: >> Dear all, >> >> I get...

Thank you Ege for your reply, > In general it seems like a difficult problem to separate inhomogeneity and anisotropy from each other this point is indeed not very clear to me. If the homogeneous Poisson point process is defined by...

Dear list, I cannot read some of the layers (table and view) from a Postgres/PostGIS DB. Error in ogrInfo. > ogrListLayers("PG:dbname=dbname") doesn't list all the tables and views. e.g. I have two views with both...

Thank you Marcelino, I already had a look at those functions and, although they do the job, I was wondering how to analyze anisotropy in point pattern using wavelet analysis. I tried to use the WaveletComp package, but with no...
